29,360 FIBER REINFORCED THERMOSETTING RESIN COMPOSITION WITH COATED FIBERS FOR IMPROVED TOUGHNESS Heat curable compositions of reinforcing fibers (filaments), a thermosetting prepolymer or prepolymers and an effective amount of a curing agent or agents in which the fibers have been precoated with a fiber- and matrix resin-reactive elastomer are described. The compositions are useful to form composites of high fracture toughness and compressive strength which, in turn, can be formed into structural members such as aircraft parts. Processes for applying an elastomer coating to fiber tapes, fabrics and rovings are also described. |
